What is available here?

• A stable MatPortal dataset identifier and machine-readable metadata.
• Public source/documentation links for the external portal or repository.
• No MatPortal-hosted RDF graph, RDF resources, GraphRAG evidence, or SPARQL graph query yet.

Use the browse page sorted by RDF resources to find public datasets with named graphs, entity pages, SPARQL starters, and GraphRAG evidence.

File preview

Preview metadata is available, but no preview rows were returned.

No public graph releases are available for this dataset yet.

RDF resources

Entity previews will appear after public graph indexing.

Ask this dataset with GraphRAG

GraphRAG searches MatPortal's public dataset metadata, named graph metadata, indexed RDF resources, and facts. It does not copy or vectorize every external file or raw distribution.

Ask a question above to get a graph-aware answer and a safe SPARQL starting point.

  "description": "The extracted Turtle (TTL) file is an RDF export of the knowledge graph created in the HybridDigital project. It contains the project’s graph content in the form of subject–predicate–object triples, i.e., explicit semantic statements rather than tabular records. The graph represents knowledge about hybrid material specimens and related research outputs, covering both experimental and simulated data. It captures the involved physical entities (e.g., specimens and their constituents), the relevant processes (e.g., manufacturing and testing activities), and the resulting information artifacts (e.g., measurements, computed results, and derived assessments). For semantic alignment, the graph follows a layered ontology approach: BFO (Basic Formal Ontology) is used as the Top-Level Ontology (TLO) to provide the foundational categories for entities and processes. CCO (Common Core Ontologies) is used as the Middle-Level Ontology (MLO) to supply reusable mid-level concepts and relations that structure scientific/engineering information, measurement representations, and artifact-related modeling. Domain-specific terms (project/manufacturing/materials concepts) extend this foundation where needed.",
